Atlantoaxial fixation–anterior or posterior approach: Critical review

Journal of Spinal Surgery, 2016
Atlantoaxial facet joints have been proposed as the center of mobility and also center for instability of the atlantoaxial region. Because of the high mobility of the atlantoaxial (C1-C2) motion segment, fusion rates at this level have been substantially

Occipitoatlantal and Atlantoaxial Dislocation [PDF]

, 2004
Vertical distractive forces at the craniovertebral junction can affect the occipitoatlantal joint or the atlantoaxial joint. These lesions are part of the same spectrum of injuries. They share the same mechanism of injury and high mortality rate.

C1–C2 Instability Associated with Periodontoid Inflammatory Tissue Leading to Subarachnoid Hemorrhage: A Case Report and Review of the Literature

Indian Journal of Neurosurgery, 2015
The authors present a case of atlantoaxial instability associated with C1–C2 inflammatory tissue leading to subarachnoid hemorrhage. A 65-year-old male patient arrived in June 2011 to the emergency unit for cervical pain and fever.

Biomechanical Evaluation of the Stabilizing Function of Three Atlantoaxial Implants Under Shear Loading: A Canine Cadaveric Study [PDF]

, 2015
OBJECTIVE: To compare the biomechanical properties of a ventral transarticular lag screw fixation technique, a new dorsal atlantoaxial instability (AAI) clamp, and a new ventral AAI hook plate under sagittal shear loading after transection of the ...

Subluxação atlantoaxial canina [PDF]

, 2009
The atlantoaxial subluxation or luxation is an instability of this articulation that produces excessive flexion of this joint causing the cranial aspect of the axis to rotate dorsally into the vertebral channel with subsequent spinal cord compression ...

Hakan HANIMOGLU Bilateral C1-C2 Claw for Atlantoaxial Instability Atlantoaksiyel ‹nstabilite için C1-C2 Pençe Uygulamas› [PDF]

, 2009
OBJECTIVE: Atlantoaxial stability can be achieved by laminar hook systems via posterior approach. This technique is much more safer than using screws. We presented our experience with the C1-C2 claw procedure.

Atlas Lateral Mass Screw Fixation in Atlanto-Axial Instability, Clinical Case Series

Egyptian Spine Journal, 2013
Background Data: Segmental spinal screw fixation has been used effectively for subaxial spine instability for long time. However, atlantoaxial fixation is still challenging due to complex topographical anatomy.
